Title: Polishing composition for copper metal and manufacture of semiconductor device
Inventor: HIRABAYASHI HIDEAKI
IPC: C09K13/00
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To enable an etching-back process to be carried out in a short time by a method wherein polishing composition for copper metal comprises a first organic acid which reacts on copper, is non-soluble in water, and generates a copper complex, a second organic acid which has a carboxyl group and a hydroxyl group, abrasive particles, oxidizing agent, and water. SOLUTION: This polishing composition for copper metal comprises a first organic acid, a second organic acid, abrasive particles, oxidizing agent, and water. The first organic acid reacts on a copper hydrate, is not soluble in water, and generates a copper complex more fragile than Cu. 2-quinoline carboxylic acid or 2-pyridine carboxylic acid is utilized as the first organic acid. The second organic acid is possessed of a carboxyl group and a hydroxyl group. A lactic acid, a tartaric acid, a mandelic acid, or a malic acid is utilized as the second organic acid. By this setup, an etching-back operation can be carried out in a short time, and a conductive member such as a very accurate buried wiring layer can be formed.

Title: Upper looper mechanism for sewing-machine
Inventor: TAKAGI ATSUHIRO
IPC: D05B57/06
Filed: 1989-09-14
Abstract: PURPOSE:To prevent the abrasion or seizure of slide parts, by a method wherein at least either of the slide parts between an upper looper-mounting stand and a guide member is formed of ceramics, and a microlubricating means whereby an extremely small amount of lubricating-oil is fed on their slide parts, is provided. CONSTITUTION:Since a ball 14 located in an adjusting hole 13 restricts the amount of lubricating-oil flowed from a small hole part 17 to a drain oil hole 12, the lubricating oil discharged from the drain oil hole 12 is made extremely small. Furthermore, when a nut 16 is loosened and then the length of the engagement of an adjusting screw 15 is adjusted, a holding space for the ball 14 in the adjusting hole 13 is adjusted, and hence the amount of the lubricating oil discharged from the drain oil hole 12 can be adjusted. In the operation of a sewing machine, although a rod part 41 of an upper looper-mounting stand 4 slides at a high speed in a guide hole 64 on an upper looper guide 63, chromium (III) oxide ceramics are flame-sprayed on the surface of the rod part 41 and the upper looper guide 63 is made of silicon carbide ceramics, and hence abrasion or seizure is not caused even if the lubricating oil fed to the slide parts is extremely small. On the other hand, a workpiece or thread is not stained with the lubricating oil even if the amount of the lubricating oil is not controlled carefully.

One resin well 5 for the main resin material and one accumulator 16 for extruding the main resin material from a the resin well 5 are thereby enough for the purpose and it is therefore possible to make the apparatus smaller. As the apparatus is constituted in such a structure that the sub resin material is extruded from the nozzles 24, 25 of the ring part material 17 set in the resin path 12 where the main resin material is being transferred under pressure, their resin wells 5 can be placed separately without any mutual heating influence each other.
